When, in the heat of (normally drunken) passion, a woman's dirty tampon is pulled out and set in a glass. Typically this glass will include some sort of leftover alcohol, resulting in an Ironton Smoothie . This noxious cocktail is normally left on a nightstand or under a bed only to be found later by the home owner/roommate.
Damnit! I just found another Ironton Smoothie in our guestroom. You've got to tell your sister to stop that shit!
